HYDRANT.

T o all whom it may concern:

Be it known that we, GEORGE E. KELLAR and ELMER O. THoMAsoN, bothcitizens of the United States, residing at Covina, in the county of LosAngeles and State of California, have invented new and usefulImprovements in Hydrants, of which the following is a specification.

ur invention has relation more particularly to a portable hydrant whichcan be detachably secured to a stand pipe of an irrigation pipe line.

In the irrigation of large ranches or orchards in semi-arid countries,where irrigation is absolutely essential to the production of crops ithas previously been the custom to install concrete pipe lines for thepurpose of distributing the water economically to various portions ofthe ranch or orchards. These pipe lines are connected to a source ofwater supply, and at intervals along the line and cross connectinglines, (preferably about 50 feet apart) cement stand pipes are erected.The purpose of the stands being to render the irrigation of all sectionsof the ranch a comparatively easy and simple matter. These stand pipesare preferably controlled by suitable valves of the general typeillustrated in the drawings. By means of these valves attached to thestand pipes, a field of grain, alfalfa or the like, adjacent the standpipes can be flooded or irrigated as the circumstances demand. In theirrigation of especially large ranches of two thousand acres or more ithas been found to be impracticable from an economical standpoint andotherwise to have more than a single pipe line, and in such instances ithas been customary to attach a temporary pipe line to a stand pipe so asto render it possible to flood large sections at a distance from thepipe line. This method has been found to be entirely satisfactory,resultino' in a great saving in the initial expense ofa installation,but when connecting to a stand for this system of irrigation theoperator has been obliged to suffer much personal discomfort. occasionedby the uncontrolled fiow of water when making the connections. By theuse of our improved hydrant the above recited inconveniences are largelyovercome, and an operator is enabled to first make his temporaryconnections to a stand before operating the valve.

Specification of Letters Patent.

Application filed October 5, 1908.

Patented Oct. 11, 1910. Serial No. 456,116.

O ur device consists essentially in a metallic casing provided with anoutlet, designed to be detachably secured to a stand pipe, and means arevalve of the stand can be ope-rated in comparative safety from wetting.

In the annexed drawings, Figure 1,q is a central vertical section of ourimproved hydrant detachably secured in place on a stand pipe of anirrigation pipe line. Fig. 2,- is a transverse section taken on line 2 2of Fig. 1. Figs. 3` 4 and 5,- are enlarged details of various parts ofthe valve operating mechanism.

Referring more particularly to the drawings, 10 designates a concretepipe line, provided with a stand pipe 11. This stand preferably projectsa short distance above the surface of the ground, and around its outercircumferential edge is provided with a iange or shoulder 12, whoseouter face is provided with a conical metallic band or seat 18. Securedin the pipe opening in any suitable manner, but preferably in the mannerindicated in the drawings, is a circular valve seat 14, having acentrally disposed connecting bar or yoke 15 formed integrallytherewith, from which projects upwardly a centrally disposed threadedpin 16. Operatively mounted on pin 16 is a circular valve disk plate 17which controls the flow of water from the stand pipe. As the valve abovereferred to forms no part of our invention we will not describe it morefully other than to show its connection thereto.

Referring now more particularly to Fig. 1 of the drawings 2() designatesa cylindrical casin preferably formed of sheet iron, close at the top bya head 21 preferably formed of the saine material and bolted orotherwise secured thereto. Casing 20 is preferably provided with adischarge outlet 22, bolted or riveted thereto from which the temporarypipe line (not shown) may be attached. I-Iead 21 is provided with acentrally disposed bearing 23 bolted thereto, and it is further providedwith a second bearing 24 secured in the same manner as the firstmentioned bearing. Mounted in these bearings is a valve operatingmechanism which preferably consists of a hollow provided by which the"COMPANY, or covINA, CALIFORNIA, A.

shaft 26, provided on its upper end with an operating handle 27, securedthereto in any suitable and convenient manner. To the lower end of shaft26 and in screw threaded engagement therewith is a bearing block or head28 to which are pivotally secured a plurality of bell crank levers 29,each being provided on its lower arm 30, and preferably at or near the`end thereof with an inwardly projecting lug or dog 31 adapted to enteran aperture 32 formed in the central bearing or spanner nut 33 securedto the valve. The upper arms 34 of these bell crank levers projectinwardly toward each other directly beneath the lower end of shaft 26.Mounted in shaft 26 as particularly illustrated in Fig. 3 of thedrawings, is a spring operated rod 35 mounted in bearings 36 attachedrespectively to the top and bottom of the shaft. This rod isA rovided.with an operating disk or hand holpd 37 and attached to the rod is acollar 38. Interposed between collar 38 and the lower bearing 36 is acoiled compression spring 39 which normally forces rod v35 upwardly andpressure foot or disk 40 out of engagement with the bell crank levers29. When rod 35 is forced downwardly disk 40 contacts with the upfperends of the bell crank levers 29 and orces the lugs out of engagementwith the apertures 32 formed in the central bearing 33 which is securedto the circular valve plate 17. In this way a detachable clutch isformed.

Casing' 2O is preferably provided on its outer cylindrical surface witha plurality of bearing lugs 41 arranged in pairs, through the apertures41 of which are adapted to pass rods 42 which are hooked on their endsas at 43 and adapted, when rotated to engage the flange 12 formed on theupper outer edge of the stand pipe 11. The upper ends `Vof these rodsare preferably screw threaded and are provided with winged thumb nuts.44 by means of which the casing 20 is forced into a water engagementwith the ange 12 on the stand pipe.

Y The casing 20 is formed of sheet metal, so that it is not a rigidcylinder as it would be 'if formed of cast ironor similar metal. By

forming the casing of sheet metal in this way, it has a desirableelasticity when it is being clamped upon the conical seat, and its loweredge adapts itself to the form of ,the seat and forms a tight joint, andattention is called to the fact that on this account it is unnecessaryto form a beveled or conical lower edge on the casing.

The operation of the device is as follows -lVhen it is desired to lead atemporary line to any particular section of the ranch or field theportable hydrant is con veyed to the stand pipe nearest to that section.The casing is first placed over the stand pipe and the hooked rods arerotated into engagement with the flange 12 after which the thumb nutsare tightened so that the casing will be sustained in an upright andwater tight position on the stand pipe.

Hollow shaft 2G is then forced downwardly, pressure being applied todisk 37 so as to force the bell crank levers 29 outwardly so that thedogs 3l will drop into thc apertures 32 formed in the centrally disposedbearing 33. After the lugs 31 have entered the apertures in the bearing33 thc shaft 2G is rotated so as to disengage the valve plate from itsseat. After which shaft 2G is drawn upwardly out of the way into theupper part of the casing 20, the shaft being secured in its drawn upposition in any suitable manner but preferably by means of a set screw45 secured in bearing 24.

It will be observed from the foregoing description that we have provideda. portable hydrant by means of which a temporary pipe line may beconnected to a stand pipe with little or no inconvenience and avoidingall danger of the wetting of the operator.

Having described our invention, what we claim is 1. A stand pipe havinga flange with a substantially conical seat on the upper side thereof, acylindrical casing of pliable sheet metal open at its lower end having aplain untapered lower edge resting upon said conical seat, a disknormally closing said stand pipe, a rotatable shaft mounted in saideasing and means for connecting said shaft with said disk to raise saiddisk to permit a flow through said stand pipe, said casing having adischarge outlet therefrom.
